Automatic Short Detection
A feature truly unique to the Velocity line of power amps is Automatic Short
Detection circuitry. Typically, shorting the outputs of a high output power amplifier will
cause amplifier failure and severely damage internal components. The Automatic
Short Detection circuit in the Velocity 250 will automatically detect any shorts which
may inadvertently occur across the amplifier's outputs and immediately shut down the
unit to protect it against internal damage.
Should this condition occur, switch the unit off for approximately 10 seconds and
make sure that the cords from the amplifier outputs are properly connected. When the
power is turned on again with the proper connections, the amplifier will operate
normally. It is important to note that two outputs from the amplifier should never be
connected to the same speaker, as this would be equivalent to shorting the outputs
together and will cause the unit to shut down.
In the unlikely event that the proper connections have been made and the unit still
shuts down, we strongly recommend that you first contact our Customer Support
Department at the phone or fax number shown on the back cover of this manual
before taking the unit to a dealer or repair shop for servicing.
Definition Control
When playing with other musicians, it often becomes a problem that the guitar
can get "buried" under the other instruments and cannot be distinguished easily. The
front panel Definition control gives the effect of bringing the guitar out of the cabinet
so that it can be heard despite the other instruments. Although it does not actually
effect the volume of the amplifier, the Definition control can be adjusted so that the
guitar becomes more audible when playing with a band.
Turning the Definition control fully counterclockwise bypasses the definition
circuit, while turning it fully clockwise provides maximum definition.
